| 2026-04-22 11:04:21 +0000 | <nmeum> | yea, makes sense |
| 2026-04-22 11:04:00 +0000 | <merijn> | nmeum: i.e. imagine `StateT s (EitherT e IO) a`, it ends up doing `runStateT` + `runEitherT` to turn it into `IO (Either e (s, a))` and then rewrapping that. But if the EitherT (or MaybeT) early aborts you don't get a state to return. |
| 2026-04-22 11:02:14 +0000 | <merijn> | nmeum: The problem is that catch is effectively unwrapping/rewrapping the stack, and there's no general way to make e.g. `StateT` handler that |
| 2026-04-22 11:00:03 +0000 | <nmeum> | hm, that would presuppose changing the entire internal state representation of my monad. I think I would rather throw a custom exception which also includes the state or something along those lines then |
| 2026-04-22 10:58:24 +0000 | <merijn> | nmeum: Or rather, in that scenario you probably just want a Reader of an IORef/MVar to access the state |

| 2026-04-22 10:24:47 +0000 | <nmeum_> | I have a question regarding Control.Monad.Catch: I do exception handling via `catch` in the context of a stateful monad `m`, in the exception handler `(e -> m a)` I want to access information about the state of my monad in which the exception occured. however, the exception handler action is executed in the state of the `catch` caller. how do access the error `m` state? |
